>My current config is as follows: This one:
>reject_rbl_client zen.spamhaus.org, Includes these three, so there's no point in using them. >reject_rbl_client dnsbl.njabl.org, >reject_rbl_client sbl.spamhaus.org, >reject_rbl_client cbl.abuseat.org, This one: >reject_rbl_client t1.dnsbl.net.au, doesn't exist any more. (Don't you ever check?) This one: >reject_rbl_client dul.dnsbl.sorbs.net, has been egregiously mismanaged. It was recently sold back to the original owner so it may improve, so I wouldn't use it now. The PBL component of zen does better what this dul tries to do. These two are OK: >reject_rbl_client psbl.surriel.com, >reject_rbl_client bl.spamcop.net, I also am seeing a lot more spam, but it's mostly coming from shared sources like Yahoo and Verizon, so DNSBLs won't help unless you're willing to lose a great deal of legitimate mail. You should also use domain lists in your body filters. If you're using a recent version of spamassassin, they're configured in automatically. R's, John
